1/1
– Cache difficulty/terrain rating shorthand. The difficulty
number is always presented first, followed by the terrain rating.
Each number can range from 1 to 5 in 0.5 increments. A 1/1 cache is
the easiest to find and get to. A terrain rating of 1 indicates that
it's handicapped accessible, while a terrain rating of 5 indicates
extreme terrain, or that specialized equipment (climbing gear, boat,
scuba gear, etc.) is required.

Additional
Logging Requirement
– A
condition, beyond merely finding the cache, that must be met in order
to be allowed to log a cache as a find. The owner reserves the right
to delete logs that do not follow the requirements. While cache
owners are allowed to set logging requirements, the more outlandish
requirements are not looked well upon by the caching community. The
requirements may be listed on the cache page, or in the cache
container.A
Breeder Cacheis
one example of a logging requirement. Update: With the exception of
Challenge Caches, Geocache.com is no
longer recognizing Additional Logging Requirements.

ATCF
– “As The Crow Flies”. Point to point mileage,
irrespective of roads or barriers. Note that it's not a true
point-to-point distance, as the distance calculated by a GPS is
actually measured following a mathematical model of the curvature of
the earth.

Battleshipping
– Attempting to determine the whereabouts of a Mystery cache by
placing caches of your own in the area. By locating the areas where
caches are not allowed, it is believed that the general location of
the hidden cache can be determined. This almost never works, as
Reviewers will easily notice this behavior, and take steps to foil
the attempt.

Beach
Tube – Lightweight, plastic water-tight cylindrical
container, typically used to hold car keys and money while swimming,
boating, or surfing. Usually has an attached cord to hang it around
your neck. Can be used for micro-caches.

Bison
Tube
– Small,
metal, water-tight cylindrical container that can be used for
micro-caches. Small enough to fit on a keychain, and normally used to
hold pills. The name is derived from the company which manufactures
most of these types of tubes, Bison
Design.

Blinky
– Often
used as another word for Nano. In reality, a
“blinky” is a small light, using a button battery and
micro LEDs. The are intended to be attached to clothing, or even as
earrings. They come with a powerful base magnet, and a similar
removable magnet, to allow it to be attached to clothing without the
need of puncturing the fabric. The electronics and battery can be
removed in order to create a Nano cache with a magnetic base.

Bookcrossing
– A
bookcrossing cache is one designed for the exchange of books. Like
Where's Georgedollars,
a bookcrossing book is registered on-line (at www.bookcrossing.com),
and the owner receives email notification when someone retrieves the
book and logs it on-line.

Bookmark
– A
Premium Memberfeature
that allows you to store links to caches in owner-defined Bookmark
Lists. Each bookmark can be given a title (or default to the
cache title), and a note can be attached.

Bookmark
List
– A
collection of Bookmarks. Each Bookmark List
has its own owner-defined title and descriptive text. An automatic
e-mail function can be set for each list. When active, an e-mail will
be sent to the list's owner whenever a log is posted to a cache on
the list. This is similar to the Watchlist,
but doesn't alter the listing of the number of people watching a
cache. Bookmark Lists can also be either Private (the default), or
Public. If set to Public, anyone you share the URL link to the list
page will be able to view it, and, if they're a Premium Member, also
rate the list. If left Private, only the owner can view the list.

Breeder
Cache
– A
cache that has an Additional
Logging Requirementplaced
on it by the owner, that requires the cache-finder to place a new
cache of their own, in order to log a find on the original cache. In
some cases, a breeder cache may contain smaller cache containers
inside, for the finders to use. Some look at breeder caches as a way
to promote the placement of new caches in sparse areas. Others see
them as encouraging the placement of poorly conceived “junk”
caches, just to satisfy the logging requirement. Sometimes known as a
“Seed Cache”.

CAAR-
“Caches Along A Route”. A Premium
Member feature that allows you to create a driving route between
two points, and all the caches within a specified distance from that
route are returned in the Pocket Query.

Cache
Machine
– When
a number of cachers form a group for the purpose of finding a large
number of caches in a relatively short period of time. These are
usually fairly easy traditional caches that can be found quickly.
Like a Power Trail, it's another way for
people to easily increase their Find count. As such, it is looked
down upon by some.

Cacher
– One who participates in geocaching.

Challenge
Cache – A cache that requires you to fulfill some type of
caching challenge before you may search for and log the primary
cache. A common challenge is the “Alphabet Challenge”,
which requires that you find at least one cache starting with each
letter of the alphabet. There may be other conditions as well, as
long as they are related to geocaching.

CITO
– “Cache In, Trash Out”. The act of removing and
disposing of trash you may find while searching for a cache. CITO is
also a special type of Event Cache, where cachers get together to
clean up a park or public space.

CO
– “Cache Owner”.

Codeword
Cache – A codeword cache does not have log book, but
instead, you are required to email back to the owner a code or
password placed at the site. These were allowed for a very brief
period of time, but they soon gave rise to a number of worthless,
uninteresting caches. Since they're really nothing but Virtual
caches, minus any interesting subject matter, they were quickly
banned from geocache.com. This type of cache is sometimes known as a
“Password Cache”.

Comma
– To “get your comma” means that you have achieved
the milestone of having at least 1,000 cache finds, and thus, your
find count now contains a comma.

Constellation
– The configuration of GPS satellites overhead at any specific
time. Some constellation configurations are better than others for
calculating your position.

Decon
Kit
– U.S.
military decontamination kit box, approximately 2.5” x 3.5”
x 1.5”. Sold by military surplus stores. Often used as a
mini-cachecontainer.
Durable and waterproof under normal use. Warning labels need to be
removed (painted over or sanded off) prior to use.

Dipping
– The
act of logging a Travel Bugor
GeoCoininto
a cache, and immediately logging it back into ones possession.
Someone might “dip” a Travel Bug or GeoCoin in order to
register miles traveled before physically handing off the cache to
someone else. Some people use a “personal traveler” to
track their miles between caches, and will “dip” the
traveler into each cache they find.

DNF
– “Did Not Find”.

DPM
– Including the letters “DPM” in a cache log was a
once-secret way to indicate the cache was of low quality. DPM is an
abbreviation for “des palourdes mortes", which is French
for “the dead clams”. The entire French phrase is “Les
longs sanglots des palourdes mortes blessent mon coeur avec un
languor monotone pendant qu'ils dansent à minuit", which
translates to “The long sobs of the dead clams wound my heart
with a monotonous languor as they dance at midnight”. The idea
was to include this phrase in a cache log to clue in others that the
cache was of low quality. Rarely actually used, as the meaning of DPM
quickly spread throughout the geocaching community, and its secrecy
was lost.

Drunken
Bee Dance
– The
movements of a geocacher, trying to pinpoint Ground
Zero, chasing the directional arrow first one direction and then
another, has been termed the Drunken Bee Dance.

Film
Can – 35mm film container, the archetypal container for
micro-caches.

Fizzy
Challenge
– A
Challenge Cache that requires the
cacher to find and log one of each combination of the Terrain and
Difficulty ratings, a total of 81 caches, in order to complete the
challenge. Sometimes called a Fizzy Square.

Frisbee
Rule – A guideline first proposed by geocacher Criminal in
a May 7, 2003 forum message. It basically states that it should not
be necessary to ask permission to place a geocache anywhere that you
would not be required to ask permission to play Frisbee. It should be
noted that this is not geocaching.com's official position.

FTF
– “First To Find”. The first person to locate a
cache after it has been placed.

GCxxxx
– The
GCxxxx waypoint identifier is just that, an identifier. It has little
other significance, beyond acting as a unique common identifier. Some
GPSrunits
can only accept waypoints of six characters or less, so the generated
ID has a maximum length of six. The GCxxxx ID is actually derived
from the sequential ID number assigned to each cache page when it's
submitted for publishing. The first 2 characters are always “GC”.
Originally, the next four characters were created by simply
converting the ID number to base-16. But it became apparent that that
scheme couldn't create enough IDs for the fast growing sport. In
April of 2003, a new scheme was put into place. All cache IDs after
CGFFFF would be created using a base-31 scheme. The characters used
for the base-31 conversion are 0123456789ABCDEFGHJKMNPQRTVWXYZ (the
letters ILOSU are omitted). When converting from a base-31 waypoint
ID back to its original sequential ID, you have to subtract 411120,
to account for the value change between GCFFFF under the old system,
and GCG000 under the new system. Update:When
the end of the 6 character identifiers (GCZZZZ) was approaching, it
was decided to scrap the 6 character limit. At that point, many of
the newer models of GPSrs could handle longer waypoint names, and
off-site software existed to allow users to customize their waypoints
to accommodate their particular GPS unit.

Geocachers'
Creed
– A
voluntary set of guiding principles that describes how geocachers
should, in general, act. It was developed by 60 cachers in open
forums to orient new players to the ethos of the caching community
and to guide experienced players in questionable situations. You can
find the Geocachers' Creed at www.geocreed.info.

GeoCoin
– Coin-size
tokens especially made for individual cachers or caching groups. Some
may be very elaborate metal coins with tracking numbers stamped on
them and encased in plastic. On the other end of the scale are
home-made coins made from a wooden disk, and hand-marked with an ink
stamp. Some coins use the same tracking system as Travel
Bugs. The same general rules that apply to Travel Bugs apply to
these GeoCoins.

Gladware
– A generically used term for cheap, disposable plastic food
containers. Compared to reusable containers, they make poor cache
boxes, as they don't seal as well, and don't stand up as well to the
environment.

GPSr
– A
GPS receiver. The “r” refers to “receiver”,
to differentiate the unit from the entire GPS system. The GPS system
is comprised of three parts: The Space
Segment,
which is comprised of the orbiting satellites (SVs);
the Control
Segment,
which are the groundbased monitoring facilities; and the User
Segment,
the actual receivers.

GPX
– A
cache database file format. Files in the GPX format are available
only to Premium Members. This format contains
virtually all the information available on a cache page, plus the
last 5 logs made to the cache, as well as any logs the person
requesting the file may have made to the cache. GPX files can be
requested from a cache page, or via Pocket
Queries. See also “LOC”.

Ground
Zero – The point where the coordinates displayed on your
GPS exactly match the coordinates given for a cache. Sometimes
abbreviated as “GZ”.

Huckle-Buckle-Beanstalk
– A
method of group caching, which takes its name from a classic
children's game. When a member of the group spots the cache, they
walk elsewhere (to not give away the cache's location), then call
out, “huckle-buckle-beanstalk!” (or whatever word or
phrase the group has decided on). This continues until everyone in
the group has either spotted the cache, or given up, after which the
cache is retrieved and logged. Compare this to the Three
Musketeersmethod.

Hula
Wave – Some GPS receivers (mostly Magellan units)
automatically engage a location averaging function when it detects
that the unit is moving slower than a certain speed. To avoid this,
the “hula wave” is used. This involves holding the unit
to your extreme right, then quickly moving it to your extreme left
(or vice-versa). The unit will detect this as movement greater than
the prescribed speed limit for averaging, and will temporarily turn
averaging off.

IBTL
– “In Before The Lockdown”. Forum usage only.
Indicates that the poster thinks the forum thread will soon be forced
closed. Not exclusive to geocaching.

LEO
– “Law Enforcement Officer”.

LN
– “Left Nothing”.

LOC
– A
cache database file format. The LOC format is available to all
members. Only the most basic cache information is included in a LOC
file. LOC files can be requested from a cache page, a Pocket
Query(for
Premium Members), or from a search list. See
also “GPX”.

Lock
& Lock – A food-storage system that features a recessed
soft rubber gasket in the lid, and a hinged latching mechanism on
each edge of the lid, which snaps into the container's sides. A
excellent choice for a geocache container, it comes in a variety of
sizes, can be opened and closed easier than an ammo box, and remains
waterproof over time. Its downside is that its plastic surface can be
difficult to paint, if it requires camouflage. The name “Lock &
Lock” is often applied to similar locking storage products,
such as Snapware.

LPC
– “Lamp Post Cache”. A very common hiding place for
micro caches, this exploits the fact that the shroud (or “skirt”)
on lamp posts that cover the anchor bolts are usually not secured,
and can be lifted up to provide a hiding place. The term LPC is
sometimes intended to be a derogatory reference, since LPC hides are
generally all the same and require little skill or imagination.

Markwell
– Used in the forums only. To “Markwell” is to
respond to a message with a link to another thread where the posted
question has already been answered. Named after the geocacher
Markwell.

McToys
– Originally referred to the toy give-aways that come with a
Happy Meal. In general, it now refers to any cheap trinket that may
be found in a cache box. The term is usually used in a derogatory
manner.

MEFF
– “Most Esteemed First Finder”.

Member
– Technically,
anyone with a geocaching.com account is a member. But the term
“Member” usually refers to those with a paid Premium
Membership. Premium Members can have more caches on their watchlist,
can run Pocket Queries, and have access
to caches that have been designated for Premium Members only (see
“MOC”).
Members who subscribed during the first year that subscriptions were
available, are designated Charter Members. Other than the name, there
is no difference between a Premium and Charter membership.

Micro-spew
– A usually derogatory term for the proliferation of micro
caches placed in obvious and uninteresting locales. The classic
example of this is the micro hidden under the base skirt of a parking
lot light pole.

Mini-Cache
– The
long-time “missing” cache size. Currently, there is not
an officialcache
size category for cache containers that are larger than a “micro”,
but smaller than a “regular”. So the geocaching community
invented the mini-cache. Mini-caches have room for a limited number
of small trade items, and may be big enough to hold a small pen (see
“Shorty Pen”).
The classic mini-container is the military Decon
Kit. Update:In
the fall of 2004, the cache size “small” was finally
added to handle the mini-cache size. The term “small” was
chosen over “mini”, to give it a unique single-letter
abbreviation (avoiding confusion with “micro”).

Mitsuko
– Geocaching's
most famous Sock Puppet. Created by
Choberiba, the Mitsuko persona was that of a young, attractive
Asian-American female. Images of the Japanese model Akane Souma were
used to complete the deception.

MKH
– “Magnetic Key Holder”. The hide-a-key box,
usually intended to conceal a car or house key, can be utilized as a
ready-made micro container. Since they are usually not water tight,
logs need to be within small zip-lock baggies, if the container is
going to be out in the elements.

MOC
– “Members
Only Cache”. A Members Only Cache is one that's reserved for
Premium Members (see “Member”).
MOC caches are designated with a
icon. Only Premium Members can display a MOC cache page, and
consequently, only Premium Members can log a MOC.

Muggle
– A non-geocacher (taken from the Harry Potter series of
books). Also “GeoMuggle”.

Muggled
– The discovery of a cache by a non-geocacher. Also
“GeoMuggled”. Although non-cachers are encouraged to
“play along” should they come across a cache, when
someone refers to a cache as having been muggled, it almost always
means it was stolen or vandalized.

Nano
– An unofficial cache size. A nano cache is usually
considerably smaller than the typical micro. One popular container is
approximately the size of an eraser on the end of a pencil. They
usually have a magnetic base to keep them in place. A nano container
is sometimes referred to as a “Blinky”.

NIAH
– “Needle In A Haystack”. A small cache placed in
an area where there are a great number of possible hiding locations.

OCB-
“Original Can of Beans”. One of the items placed in the
very first geocache (actually called a “stash” at the
time). The can, which was never traded for, was later recovered. It
has been made into a Travel Bug, and
occasionally makes appearances at various geocaching get-togethers.

P
& G – “Park and Grab”. A easy-to-find cache
that you can get very close to by car. Sometimes written as “P-n-G”
or “PNG”.

PAF
– “Phone A Friend”. Usually done in the field,
via cellphone. This may take one of two forms. If the cacher is
hunting a cache without the cache page information, he or she may
call someone who will look up the cache page and relay the
description and hint. In other cases, the cacher may phone someone
who has already found the cache, in hopes of getting additional
information about its location.

PI
– “Poison Ivy”. Used generically to include poison
oak, and poison sumac.

Pirates
– A short-lived phenomenon where rogue geocachers would steal
caches, and then either: a) destroy the cache; b) hold it for ransom;
or c) move it to another location, leaving only a note behind with
the new location. A number of minor variations were also used. A late
attempt was made by some pirates to legitimize the activity, by
making it an opt-in, non-destructive activity. But by that time,
pirates had generated so much ill-will among mainstream geocachers
(which still exists) that they were drummed out of the sport.

Plunder
– Similar
to “Muggled”,
a plundered cache is one that has been stolen or vandalized. However,
there is a slight difference in meaning. Saying a cache has been
plundered leaves open the possibility that the act was not done by
accidental finders. See also “Pirates”.

Pocket
Cache
– A
pocket cache is a cache carried on one's person, usually to
geocaching events. Often these are actual caches that the owner has
moved from their assigned location. Since geocaching.com no longer
supports Traveling Caches, and the
removal of active caches can cause confusion for those seeking them
in their posted location, Pocket Caches are not condoned. Using a
cache in this manner may cause it to be permanently archived and
locked.

Pocket
Query
– A
cache query engine available only to Premium
Members. A wide variety of search and filter parameters are
available. The resulting query is emailed to you in either GPXor
LOCformat,
on whatever schedule you set. The term “Pocket Query” is
often used to reference the actual file that the query generates.

Podcache
– A puzzle or multi-cache which utilizes spoken or aural clues
that the cache-finder listens to on-site via a portable MP3 player.
The finder downloads the audio file from a link on the cache page,
uses the GPSr to navigate to the starting point, then uses the
instructions from the audio player to locate the cache. There may be
additional puzzles and GPS navigation required along the way.

Power
Trail
– A
path with a large number of easy traditional caches placed every
1/10th of a mile. Like a Cache Machine,
it's another way for people to easily increase their Find count. As
such, it is looked down upon by some.

Preform
– A micro container resemble a wide test-tube, made of
transparent plastic (usually clear but sometimes tinted), with a
screw-on cap. Preforms are actually the “blanks” which
are heated and blown into a form to create soda bottles. They are
very durable and waterproof, making them a good choice for a
micro-size cache container. The main downside to preforms is that
they generally have to be purchased in bulk quantities, rather than
individually.

Project
A.P.E. – A promotional tie-in with 20th Century
Fox, to publicize their remake of the movie Planet of the Apes. A
number of caches were set up around the country, stocked with
promotional items from the movie. A few of these caches still exist,
and now function as Traditional caches. For the curious, A.P.E. stood
for Alternative Primate Evolution.

Reviewer
– A
local volunteer who validates a cache submission prior to the cache
being posted. Sometimes referred to as an Approver, but Reviewer is
the preferred term. Reviewers do not personally visit a cache site,
but confirm that the cache, as presented in the submission, adheres
the the posted Cache Placement Guidelines.

Ringbone
– A
reference to ringbonein
a forum post (usually in the form of the question “Why does my
post say ringbone”) is a sly reference to the use of a Sock
Puppetcreated
to post messages, in order to bolster one's viewpoint. The term goes
back to a forum thread in early March 2004. A poster with the name of
“ringbone” attempted to create a new account (named
“Oronma”, an anagram of “A Moron”), and post
a message as if he were a neophyte geocacher. However, he didn't
properly log out and back into the system, so the post appeared under
his real account. He then posted the now-famous “why does my
post say ringbone” message, again mistakenly under his real
account. He apparently figured out his error, and posted the same
message under the fake account.

ROT13
– A simple encryption scheme where each letter is rotated 13
characters up or down the alphabet. Based on one of the world's
oldest encryption schemes, ROT13 came into common use in the 1970s on
early BBS's (Bulletin Board Systems), and later on Usenet. In
geocaching, cache location hints are encoded using ROT13.

R.O.W.
– “Right Of Way”. Often, the area between a street
and the sidewalk.

SBA
– “Should Be Archived”. Log type indicating that
there is a severe problem with a cache (missing, destroyed,
inaccessible, or on private property without permission). When a SBA
log is made to a cache, a copy of it is automatically sent to the
geocaching.com administration, who then route it to a local reviewer.
The official log type is Needs Archived but the term Should
Be Archived came first, and has stuck.

Shorty
Pen
– A
ink pen that has been shortened enough to fit in a small cache
container. There are companies that sell them ready-made
(ShortyPen.com)or
you can make
your ownin
any size you want for 15¢ to 20¢ each.

Signal
– Signal is the official mascot of geocaching.com. Designed by
artist Koko, Signal is a frog with an GPS antenna on his (her?) head.

Signature
Item
– An
object used a trade item in caches, that is meant to be identified
with a specific geocacher (or group of geocachers). As such, some
people actively collect different Signature Items. Some Signature
Items, like some GeoCoins, have unique
identifiers that allow them to be tracked. For example, digitalfishcan
be tracked on-line, like Travel Bugs.

SL
– “Signed Log”.

Sock
Puppet – A false account used in a forum or chat-room
account in order to hide the true owners identity. It is a common
Internet term, and is not specific to geocaching.

Spoiler
– An on-line log entry (or photo attached to an on-line log)
that may give away the location of a cache, or in some other way
“spoil” the caching experience for others.

STF
– “Second To Find”. The second person to locate a
cache after it has been placed.

SV
– Space
Vehicle. In GPS terms, SV refers to the satellites comprising the
Space Segment of the GPSsystem.

Swag
– Not exclusive to geocaching. Contrary to popular thought,
“swag” is not an acronym, nor is it a recently invented
term. The word has been around for several centuries. It has a number
of meanings, but the one utilized in geocaching stems from “swag”
as referring to stolen or plundered loot. In more modern times, it's
come to mean free promotional items, like you might get at a trade
fair or an expo. Because of this, in a bit of creative
reverse-etymology, people have come to say that it's an acronym for
“Stuff We All Get”, which is clever, but completely
wrong. In geocaching, the usage of “swag” would just mean
the trade items found in a cache, or things that could be used as
trade items.

Tadpole
– New
forum users are given the avatar title of “Tadpole” until
they have posted at least 10 messages, at which time their title
changes to “Geocacher”. The tadpole is a reference to the
geocaching.com mascot, Signal.
Those who are Premium
Membershave
the option of changing their avatar title at any time.

The
Force – The experience gained from finding caches, which
helps one spot locations likely to be concealing a cache. Taken, of
course, from the Star Wars movies.

Three
Musketeers
– A
method of group cache hunting, which takes its name from the
Musketeer motto, “All for one and one for all.” Unlike
the Huckle-Buckle-Beanstalkmethod,
as soon as one person in the group finds the cache, the hunt is over,
and all members of the group log their find.

TOTT
– “Tool Of The Trade”. This generally indicates
that some type of tool or instrument may be required to retrieve or
gain access to a cache. The nature of the tool is usually not
specified, but there may be hints within the cache page. It could be
an actual tool, such as a screwdriver, or something as simple as a
long stick to retrieve a cache from a high perch.

TPTB
– “The Powers That Be”. Refers to the upper echelon
of the geocaching.com administrative hierarchy.

Travel
Bug – An item that travels from cache to cache. The item
has unique tracking number (assigned by geocaching.com), which allows
you to follow its journey. A Travel Bug is not a trade item,
and you are not required to leave anything in the cache when you pick
up a Travel Bug, though you are expected to place it in a different
cache in a reasonable amount of time. Some Travel Bugs may have a
specific goal, such as to reach a certain location. If a Travel Bug
has a goal, and you are unable to help it reach that goal, even in a
small way, it is customary that you leave it for someone who can
assist it in that goal.

Travel
Bug Hotel
– A
geocache with the intended purpose of acting as an exchange point for
Travel Bugs. These are almost always
Regular or larger sized containers.

Travel
Bug Prison
– A
Travel Bug Hotelwhich
requires that you leave as many Travel Bugs as you take, and/or that
you do not take more than a certain number of Travel Bugs. They are
called prisons (or jails) because Travel Bugs can get “stuck”
in them for an extended period of time, as people who find the cache
don't move any of the Bugs on, because they didn't have a Bug to
leave. In fact, only the Travel Bug owner, not the cache owner, has
the right to apply any kind of movement restrictions on a Travel Bug.
Because of this, any movement restrictions placed by the cache owner
may be ignored by the cache finder.

Traveling
Cache – A cache whose purpose is to change locations with
every find. When someone finds a traveling cache, they can place it
in a new location, and post that location in their find log. Due to
numerous problems with this type of cache (showing up in off-limit
areas, disappearing for extended periods of time, failure to log new
location, etc.), traveling caches are no longer published on
geocaching.com, but there are still a small number of them that were
grandfathered in.

Watchlist
– A list of caches for which you will receive via email a copy
of any logs made for those caches. The number of caches you can have
on your watchlist is dependent on the type of membership you have.

WG$
– Refers
to either a Where's George dollar bill or the Where's George website
(wheresgeorge.com).

YJTB
– “Yellow
Jeep Travel Bugs”. A contest held in conjunction with Jeep. The
logs and pictures for the Jeep Travel Bugs were judged for creativity
and originality in order to win Jeep gear. See also “Travel
Bug”.

This
list is compiled from words, phrases, and abbreviations found in the
geocache.com forums posts and cache logs.
